AXIS Occupancy Estimator

AXIS Occupancy Estimator is an analytic application that can be installed on a network camera. The application keeps track of how many people are currently occupying a closed area.

The application can also estimate how long the average person spends in the area.

AXIS Occupancy Estimator includes AXIS People Counter functionality.

How does it work?

The application works both in a single retail shop with just one entrance or in a store with several entrances and exits. Each entrance and exit to the building needs to be equipped with a network camera with AXIS Occupancy Estimator installed. If there are several cameras, they communicate with each other over the network in a primary and secondary concept. The primary camera continuously fetches data from the secondary cameras and presents the data in the live view. Every fifteen minutes, the primary camera sends the statistical data to AXIS Store Data Manager. Consequently, the reports generated from AXIS Store Data Manager can present the data in a minimum of 15 minutes time interval.

In addition to the instructions in the camera’s Installation Guide, there are some important steps to follow for the application to behave in the expected way:

• We recommend that you install the camera at a minimum height of 270 cm (8.9 ft).

• As a rule-of-thumb, the camera covers an area as wide as the camera’s mounting height. For details about a specific camera model, see the Camera selector for AXIS People Counter

• After installation, the covered area can be increased depending on the camera’s zoom setting.

• If the camera is mounted high enough, you can get a coverage width of 8 meters. You can cover even wider entrances by using multiple counters.

• The camera must be mounted straight above the point where people pass.

• Make sure the camera is facing straight down, in line with the ceiling.

• If you install the application before you install the camera, you can use the counting area indicated in the live view to position the camera. The counting area should go from left to right, perpendicular to the path where people cross.

• Make sure there is sufficient white light or IR illumination on site.

• Make sure that there are no continuously moving objects in the counting area. For example, do not install the camera above an escalator.

• Make sure there are no moving objects interfering in the counting area. For example, do not install the camera too close to a door.

• Avoid getting very strong light, like sunlight, and sharp shadows in the camera view.

4. Save the license key file on the computer and select the file when the application asks for it.

1. In the camera’s web interface, go to Apps, start the application and click Open.

The date and time settings are important for your camera to keep the correct time for a longer period of time, and for the statistics to be attributed to the correct time. You set the date and time in the camera’s web interface.

1. In the camera’s web interface, go to System > Date and time.

2. For more information about date and time settings, click .

You can create user accounts with different privileges, so that unauthorized staff can view statistics but not change any settings of the counter.

You create user accounts in the camera’s web interface.

1. In the camera’s web interface, go to System > Users.

2. For more information about user accounts, click .

To check if the application is calibrated for your camera, go to the Camera selector for AXIS People Counter tool.

1. In the application’s web interface, go to Settings > General.

2. Make sure Status is on.

3. In the Name field, type the name of the camera or location.

   This can be for example “Axis_Main_entrance_T_building”. All cameras need to have unique names.

4. Set Calibration mode. Do one of the following:

5. • If the application is calibrated for your camera, select Height setting. Type the mounting height in the Visual height field.

   • If the application is not calibrated, select Manual setting and click Setup. Place a person underneath the camera and adjust the size of the yellow box so that it covers just one person.

6. If you need to zoom in, do one of the following:

7. • Turn on Digital zoom and click Setup.

   • If the camera has optical zoom, you need to go to the camera’s web interface to adjust the zoom.

8. Set Direction in to Up or Down, depending on the direction of the people passing by in live view.

9. To adjust the counting area, go to Adjust the counting area.

In the live view image, the counting area is indicated by two blue lines and a red area. A person needs to pass through the red area to be counted.

Use the curvature settings to change the shape so that it is natural for people to pass through the counting area. Keep the curvature as close to a straight angle as possible.

1. Go to Settings > Counting zone.

2. To move the entire counting area up or down, use the Line offset slider. How much you can move it depends on the counting area size.

3. To adjust the height of the counting area, use the Counting zone height slider.

4. To adjust the width of the counting area, use the Counting zone width slider. How much you can adjust it depends on the camera’s mounting height.

5. To use a curved counting area, select Curved line and then adjust the radius with the Radius slider.

6. To change the direction of the curvature, click the Radius icon.

7. Click Submit to save the settings when you are done.

8. You might need to fine-tune the counter for the best possible performance, see Validate the system.

If you need to cover a wide entrance with several counters you can set up multiple cameras, also called Neighbor counters. To calculate how many cameras are needed to cover the entire width of the entrance, use the Camera selector for AXIS People Counter.

The primary camera overrides the following settings on the secondary cameras:

• Visual height

• Counter sensitivity

• Digital zoom

• Network & time

• Line offset

• Counting zone height

• Counting schedule

1. Mount the cameras side by side following the measurements indicated by the camera selector tool.

2. Go to the primary camera application web interface and select Settings > Advanced > Neighbor counters.

3. Select Enable as primary.

4. If you have a secondary camera that you want to connect to:

5. 1. Go to the secondary camera.

   2. Go to Advanced > Neighbor counters.

   3. Select Display connection key

   4. Click Copy connection key.

   5. Return to the primary camera.

   6. Paste the text under Connection key.

6. Note

   If you don’t have a secondary camera, you can leave the Connection key field empty.

7. Note

   If the cameras are configured to send data to AXIS Store Data Manager, make sure that only the primary camera is connected. The primary camera automatically uploads the data from all the secondary cameras as one single unit.

8. Click Submit.

9. When you have connected all cameras, go to Calibrate secondary position.

10. Place an object, for example a sheet of paper, at the exact mid-point between the two cameras. It’s very important that you place the object exactly in the middle of the two cameras since the object is used as a reference point to calibrate the cameras.

11. Drag the view of the secondary camera over the primary camera view. Try to avoid vertical offset.

13. 1. Primary camera view
    2. Secondary camera view
    3. Reference object

14. Once the calibration is done, go to Live view in the primary camera to view all of the secondary cameras.

If you can’t see the video stream from the secondary cameras in the primary camera, make sure that there are no other connections to the secondary cameras running.

One of the cameras has to be the primary. The primary camera represents the whole area and makes the estimations of the occupancy and average visit time for the whole area.

1. Enter an Occupancy name. This is the name that shows up in AXIS Store Data Manager.

2. Enter the local IP addresses for the secondary cameras.

3. • If the secondary camera connects two different occupancy areas, select Reverse In/Out direction. See Reverse in/out direction.

   • If there are no secondary cameras, leave the IP address field empty.

4. Select Full-day analysis, see Full-day analysis.

5. Select Occupancy mode, see Change to naive occupancy mode.

1. Install AXIS Occupancy Estimator on all of the cameras covering the entrances or exits.

2. Go to Settings > AXIS Occupancy Estimator.

3. Select the Secondary role.

4. Go to Settings > Advanced > Neighbor counters.

5. Select Display camera credentials.

6. Copy the IP address, username and password.

7. In the primary camera, go to Settings > AXIS Occupancy Estimator and add the credentials to the list of secondaries. See Set up a primary camera.

To calculate the occupancy levels of the two adjacent rooms connected by the same secondary camera, you must select Reverse In/Out direction in one of the primary cameras. This overrides the Direction in setting made in the secondary camera, but only for this occupancy area. In other words, this ensures that people walking out from the first room, are considered walking in to the second room and vice versa.

1. Primary camera, room 1
2. Secondary camera
3. Primary camera, room 2

The full-day analysis is selected by default.

Full-day analysis means that the occupancy that has been calculated during the day is slightly modified after closing. This is because when the data for a complete day is gathered, more details about that day is available and the application can give a more precise estimation of the occupancy during that day. The occupancy application automatically detects when the occupancy area is open or closed by observing the flow of visitors.

Consequently, full-day analysis also means that the primary camera only sends statistical data once a day to AXIS Store Data Manager.

AXIS Occupancy Estimator can be run in two modes. The application is developed for smart occupancy, however at locations where traffic and average visit time are not steady, naive occupancy can still provide additional value.

Smart occupancy mode

The smart occupancy means that the application analyses frequency of passages and in turn calculates an average visiting time, which is then used to filter away counting errors that accumulate throughout the day. The output is an estimated occupancy and average visiting time at any given time as well as a corrected full day analysis at the end of the day.

Naive occupancy mode

If you select the naive occupancy mode, the application estimates the occupancy by counting “people coming in” minus “people coming out”. This estimation is not as sophisticated as the smart occupancy mode, and the occupancy error accumulates over time. The error will be larger if there is a high flow of people and if the counter is poorly configured.

The table shows recommended occupancy mode for different scenarios, based on traffic flow and average visiting time.

If you select naive occupancy mode, we recommend that you schedule a reset of the counter. See Change to naive occupancy mode.

1. Go to Settings > AXIS Occupancy Estimator.

2. Set Occupancy mode to Naive.

3. Select when to reset the counter by moving the Reset occupancy slider.

If you don’t want to reset the counter automatically, move the slider to the right until it says Never reset occupancy. You can reset the counter at any time in the live view.

This example explains how to set up a rule to send an email when the number of people inside the premises exceeds a limit. In the example, the limit is 200.

1. Set the maximum occupancy limit

2. In the application, go to Settings > AXIS Occupancy Estimator.

3. Select Enable stateful events.

4. Enter 200 in Higher threshold.

5. Click Submit.

1. Create a rule

2. In the camera’s web interface, go to Events and add a rule.

3. Type a name for the rule.

4. In the list of conditions, under Application, select Occupancy-High.

5. In the list of actions, under Notifications, select Send notification to email and then select a recipient from the list.

   To create a new recipient, go to Recipients.

6. Type a subject and a message for the email.

7. Click Save.

The application automatically disables the counting functionality when it gets dark. If you want to limit the counting further, you can set up a schedule.

1. Go to Settings > Counting schedule.

2. To adjust start and stop times, move any of the sliders. To set individual schedules for each day of the week, select Per day schedule and then move the corresponding sliders.

Turn off the application on a specific day of the week

Clear the checkbox next to the slider.

You can configure the application so that people can no longer be identified from the camera.

Anonymize soft

This feature blocks all video streams and images from the camera. The live view still shows a blurred image which means you can still see what is going on but you can't identify people.

1. Go to Maintenance > Anonymize.

2. Click Anonymize soft.

3. To go back to normal mode, click Reset anonymization. Only users with an administrator account can do this.

Use the copy functionality if you want to copy the application settings to, for example, other cameras in the same store with the same mounting height. Camera-specific settings, such as the application license and camera name, are not included.

1. To copy the application settings, go to Maintenance > Parameter backups.

2. Click Copy. The computer saves the file in your browser’s default folder for downloads.

When you have installed and set up all cameras in the building, we recommend that you validate the accuracy and fine-tune the system. This is likely to increase the accuracy or identify any problems with the counters.

To get an overview, go to Statistics and look at the counting data for a couple of days back. If the difference between number of persons going in and out is <5% it’s a good first indication that the system is configured correctly.

If the difference is greater than that, follow the instructions inValidate the counter.

1. Go to Live view.

2. Click Test accuracy.

3. To hide the automatic counter, click Hide.

4. Click Start and manually count 100 or more passages by pressing the up and down arrows on your keyboard. You can also click In and Out.

5. If you need to start over, click Reset.

6. Click Result when you are done.

7. Check the accuracy table. Under normal circumstances, the total accuracy percentage should be 95 % or higher.

If you’re not satisfied with the accuracy of the counter, see Fine-tune the counter.

1. Make sure the camera is mounted according to the instructions in Mount the camera.

2. Go to Settings > General.

3. Go to the Counter sensitivity slider, or click Setup if the counter is running in manual mode, and do one of the following:

4. • If the counter is counting too many compared to the control figure, decrease the counter sensitivity with about 20 units or increase the size of the yellow box slightly.

   • If the counter is counting too few compared to the control figure, increase the counter sensitivity with about 20 units or decrease the size of the yellow box slightly.

5. Validate the accuracy again, see Validate the counter.

There is a light-weight version of the web interface at the URL http://<servername>/people-counter/lite/index.html. These pages can for instance be used to embed the application into systems, for example AXIS Camera Station or Milestone's XProtect Smart Client.

There are four pages available:

• http://<servername>/people-counter/lite/day.html: The page shows the day plot, the same plot that can be seen on the Statistics page.

• http://<servername>/people-counter/lite/week.html: The page shows the week plot, the same plot that can be seen on the Statistics page.

• http://<servername>/people-counter/lite/count.html: A page that shows the live count for the current day.

• http://<servername>/people-counter/lite/liveview.html: A slim version of the live view page that shows live count and the video stream with the counting area as overlay.

The menu at the bottom of the pages can be disabled by appending ?clean to the URL:s above, e.g. http://<servername>/people-counter/lite/liveview.html?clean. You can also add a lang tag before lite to display these pages in other languages, example http://<servername>/people-counter/cn/lite/liveview.html

AXIS People Counter is an application accessible on your indoor Axis camera that provides simultaneous two-way counting of people, which lets you analyze visitor trends such as peak visitor hours. It is also able to estimate occupancy levels in real-time and provide access to data on the number of people present on either the premises or in a certain area at a certain time. This is helpful when you want to understand occupancy trends that enables you to measure if the occupancy levels exceed a set threshold.

Additionally, the application can detect and notify if more than one person enters within a set time interval or move in the wrong direction. This means that if you set up the application over a one-way entrance you will receive a notification whenever someone tries to leave or if more than one person tries to enter at the same time.

The occupancy data requests fetches the total number of people entering or leaving a location and their average visit time.
